The Lost Contract is one of the Robbery Contracts available in GTA Online's Los Santos Tuners update
We'll cover the "Lab Locations" and "Transport Method" planning missions, followed by "The Lost Contract" finale, with tips for solo completion. The objective is to disrupt a Lost MC meth operation and seize their supply, with a net payout of $162,000.
Lab Locations (Planning Work)
In this mission, you need to head over to one of the Lost MC clubhouses and steal some equipment, including explosives. There are two ways you can complete this mission — aggressive or sneaky. Aggressive is self-explanatory and will require you to fight your way into and out of the clubhouse. The best method to do it is by sneaking your way in using a disguise. When the mission starts, there will be a new vehicle icon on your minimap.
Go to the vehicle location and you will find a parked black Slamvan with some Lost MC members guarding the area. Take them out and get in the van. Be careful as one of the guards has a shotgun.
Drive the van to the Lost MC clubhouse and the backdoors of the van will automatically open up for you.
When you approach the vehicle's trunk you will get an option to equip Lost MC Outfit, which will allow you to blend in with the rest of the gang members.
Before you head inside the clubhouse make sure you call in your personal vehicle, just in case things go south when you're making your way out of the clubhouse. This will allow you to escape quickly.
Make your way inside the clubhouse while avoiding bumping into the gang members, and also make sure to not stay in their cones of vision for too long or you will get detected.
Always check the room to your left as soon as you enter as it can also contain the equipment.
There is a room by the stairs that usually has a safe you can loot for some documents.
After getting the documents make your way upstairs and you will find a duffle bag with explosives inside of it. The duffle bag will be resting on a stack of beer cartons.
Once you've collected the equipment and documents, carefully make your way back out of the clubhouse and run to your vehicle.
Deliver the equipment to your Auto Shop to complete this mission. If you alert the guards, you will be chased by the Lost MC members until you are near the Auto Shop.
Transport Method (Planning Work)
In this mission, you need to find the cargo list and a transport vehicle to later deliver that cargo to the drop-off site during the finale. There are two ways you can complete the second half of this mission, but the first half remains the same.
First, you will need to make your way to Elysian Island. You can get one of two locations on the island.
When you get close to the yellow destination marker, you will see white dots appear on your minimap. These are the Lost MC members. Make sure you are on foot and not in a vehicle.
When you see the dots keep your distance and wait for them to leave the area.
Once they're gone one of the white dots will turn blue. This is the dock foreman who has the cargo list. Follow the foreman until he reaches a quiet place and his icon turns red.
Use your suppressed weapon to take him out.
Once the foreman has been eliminated you will see his cargo list on the ground. Take a picture of the cargo list and send it over to Sessanta. If the picture is not registered, zoom in on the cargo list and it should be registered.
Now we move onto the second half of the mission, where you need to find and deliver a Truck Cab to the drop-off point. Usually, there is always a truck at the docks where you get the cargo list.
All you need to do is get into the truck and drive it to the drop-off point.
However, the delivery can be made a lot more convenient if you've bought a Phantom Wedge from the Warstock Cache & Carry store. It costs GTA$2,553,600 (SecuroServ Trade Price is GTA$1,920,000). Remember, this is just an optional step if you have the Phantom Wedge. You can simply deliver the regular truck cab if you do not own a Phantom Wedge.
If you own a Phantom Wedge, make your way to the marked location shown on the map below. This is where you would usually get a marker to drop the truck. Since we are not in a truck, we can add a custom marker to reach the location in one of our personal vehicles. You can either use an Oppressor Mark II or a Buzzard helicopter.
